SPINNING-MACHINE.

Specification of Letters Patent.

Patented July 14, 1914.

Application filed November 21, 1913. Serial No. 802,232.

To all whom it may concern:

Be it known that I, ARTHUR L. SCHOELLES, a citizen of the United States,residing at Newfane, in the county of Niagara and State of New York,have invented certain new and useful Improvements in Spinning- Machines,of which the following is a specification, reference being had to theaccompanying drawings. i

This invention comprehends certain new and useful improvements inspinning machines and relates more specifically to that type known asspinning mules and has for its primary object to provide means which maybe incorporated in a spinning mule for catching and holding the end ofthe yarn during the operation of removing a full bobbin and replacingthe same by an empty bobbin, thereby preventing the yarn from windingaround the spindle.

Another object is to provide a device of this character which may beemployed upon spinning machines of the type now in general use at acomparatively small cost without the necessity of altering theconstruction of said spinning machines.

A further object is to provide a device of this character which will becomposed of a comparatively small number of parts of simple formationand which, when applied, will be highly efficient and effective in use.

With the above and other objects in view, my invention consists incertain novel constructions, combinations, and arrangements of parts tobe hereinafter more fully described, claimed, and illustrated in theaccompanying drawings, in which,

Figure 1 is an elevational view of my invention applied to a spinningmule of ordinary form, a portion of said mule being shown in order thatthe invention may be more readily understood. Fig. 2is a view similar toFig. 1, showing my invention in use: Fig. 3 is a vertical sectionthrough a portion of my invention with a spindle upon which this portionof the invention is applied, shown in elevation; Fig. 4 is acrosssectional view through the spindle with the parts of my inventionmounted thereon shown in plan; Fig. 5 is a detail plan view partly insection showing a slightly modified form of the invention; Fig. 6 is anelevational view of the modified form of clamping disk; and Fi 7 is atransverse section through the roe? shaft, showing in elevation, amodified form of up orting bracket for said shaft.

Referring more specifically to the drawings in which similar referencecharacters designate corresponding parts throughout the several views, 1designates a portion of the frame-work of a spinning mule carrying theusual rigid arms 2 at each end, one of which is illustrated in theaccompanying drawing. The usual yarn guiding arms 3 are carried by theshafts 4:, each of which has one end mounted in one of the rigid arms 2.It will be understood that a pair of guiding arms 3 is provided for eachspindle 5, said spindles being mounted in the frame-work of the spinningmule and rotated in the-usual manner. of clearness, I have shown onlyone spindle with a bobbin (5 mounted thereon, in order that I mayclearly show my invention and the manner in whichit is connected withthe above mentioned parts of an ordinary spinning mule.

My invention as herein disclosed consists of a wheel 7 provided withradially directed fingers or arms 8 and adapted for frictionalengagement upon the spindle 5' immediately beneath the bobbin 6. I havealso provided a disk 9 loosely mounted upon the spindle 5 below thewheel 7 and adapted for cotiperation with the same. The disk 9 isprovided with the depending tubular stem 10 which has an,annular flange11 at its lower end. The purpose of this construction will presentlyappear.

The lower or flanged e'nd'of the stem 10 rests upon the bearing balls 12in the cup 13 which is slidably mounted upon the spindle 5 andresiliently retained in its up permost position by a helical spring 14:which has its lower end rigidly-secured to t'he portions of theframe-work 1, through which the spindle 5 is mounted, as shown at 1'5.

The disk 9 is forced downwardly by means of the bifurcated arm 16engaged around the stem 10 and bearing upon the flange 11, saidbifurcated arm 11 being mounted upon the rod 17 carried by the collar 18which is adjustably secured upon the shaft 19, by means of a set screw20 .or the like. Each end of the shaft 19 is rigidly mounted within anarm 21 which is adjustably secured to the stationary arm 2, as shown at22, and preferably extended in a horizontal direction toward the spindle5, whereby the height of the shaft 19 may be readily adjusted, asdesired.

The shaft. 19 is rotated by a lever 23 se For the sake 34, and adapted,

. turned to and locked to eliminate all danger cured upon the same, asshown at 24, and carrying a locking dog 25 for engagement bet-ween thenotches 26 in one longitudinal edge of the outwardly directed rack arm27 of the plate 28 secured to a portion of the frame-work 1, as shown at29. It will be understood that the locking dog 25 is 1 slida bly'mountedupon the lever 23 and is resiliently retained in operative position bythe helical spring 30 around the guide rod 31 which has one endconnected with the locking dog 25 whileits opposite end is extendedthrough the guide bearing 32 on the lever, the last mentioned end of therod 31 ing securedto thereleasing finger 33, which latter is pivoted tothe lever 23 adjacent the handle end thereof, as shown at when pressedtoward the handle end of the lever 23, to withdraw the locking dog 25from between the notches 26 of the rock arm 27.

The locking dog 25 is normally engaged in the uppermost notch 26 of therack arm 27, thereby causing the bifurcated arm 16 to retain the disk 9in spaced relation with the wheel 7. When the proper amount of yarn 28has been wound around the spindle 5, the arms 3 are swung downwardly asshown in Fig. 2, as the carriage or movable part of the mul spindle 5given a half turn, thereby causing one of the arms 8 of the wheel 7 tocatch the yarn 28 and spindle. The outer end of the lever 23 is thenmoved to and locked in its lowermost position, thereby raising thebifurcated arm 16 and allowing the spring 14 to force the cup 13 anddisk 9 upwardly, pressing said disk against theyarn and gripping thesame between said disk 9 and the wheel 7.' The bobbin 6 is then removedand an empty bobbin placed inposition, after which the arms 3 are againreturned to normal position and the spindle turned to wind the yarn onthe new bobbin. The movable portion or carriage of the mule is then runin aboutsix feet, the disk 9 rotating upon the bearing balls 12 with thewheel 7 and spindle 5. As soon as a sufficient amount of yarn has beenwound upon the bobbin of the yarn slipping from said bobbin, the lever23 is again rein its uppermost posit-ion, thereby drawing the disk 9from the wheel 7 and allowing the end of the yarn to fly upwardly.

From the foregoing, it will be readily seen that I. have providedimproved and novel means for taking care of the yarn durihg operation ofremoving a filled bobbin and placing in position an empty bobbin and itwill be seen that the parts of my invention are so constructed andarranged 0 091 of this patent may be obtained for flv'e cents each, byaddressing the a losss of yarn each slightly modified form e movesoutwardly, andthe,

draw the same close to the as to eliminate all danger of the yarnwinding around the spindle and thereby causing time the bobbins arechanged. It will therefore be seen that this device will. not only savetime, but will also save a quantity of yarn heretofore wasted.

In Figs. 5, 6 and 7, I have shown'a of the invention in of the disk 9'has a pair of spaced flanges 11 in its opposite ends and the bifurcatedarm 16 is formed integral withthe' rod 17 projectingfrom the collar 18adapted to be secured-upon the shaft 19, by the set screw 20' or othersuit able securing means. The outer parallel ends of the bifurcated arm16 areprovided with alined transverse openings 35 to receive thelaterally projecting pins 36 of the which the stem- 10 segmental blocks57 for closing the outer after the same has-been stem 10 of the disk 9.In this modified form, I have also shown a slightly different form ofbracket arm 21 having a horizontal portion 38 with an enlarged aperturedbearing end 39 to receive the shaft 19. while the vertical portion 40 ofsaid bracket arm 21 is suitably perforated whereby the same may besecured to the frame l of the movable portion of the end of said arm 16engaged around the spinning mule and secured to the rigid arm 2 as inthe preferred form. t will be understood that other minor changes inthedetails of construction and arrangement of parts maybe made within thescope'of the appended claim without departing from the spirit of myinvention or sacrificing any of. the advantages of the same.

What I claim is:

I In a machine of the character set forth, the combination with a railand a, spindle carried thereby, .of a thread holding-jaw fixed thereto,a second jaw freely carried thereby and capable of movementendwisethereof relativelyto-the fixed jaw, a member loosely surrounding thespindleand coacting with the movable jaw formaintainving the jawsnormally closed, a spring in terposed between the member and rail andhaving its extremities secured thereto. means operatively engaged withthe movable jaw for separating the same from the fixed jaw against thetension of the springcontrolled member without stopping the spindle, andanti-friction means interposed between the movable controlled member. v

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.
